灵活QinQ技术在校园网中的设计与实现

高校校园网普遍存在IP盗用、IP冲突、二层广播严重等问题,且一直没有一个较为完善的解决方法。中国矿业大学校园网采用灵活QinQ+DHCP网络模式,通过BRAS建立双层标签,DHCP自动分配IP,交换机端口二层隔离,创造性的解决了这一长期困扰我们的问题。

Design and Implementation of Flexible QinQ Technology in the Campus Network

Serious problems such as IP theft,IP conflicts,as well as the second layer of broadcasting are generally exist in Campus Network and there is no sound solution ever since a long time ago.We adopted the network model of flexible QinQ+DHCP in our Campus Network of China University of Mining and Technology.In this way,the double tags can be established by BRAS,the IP addresses can be allocated automatically by DHCP,and switch ports realize layer-2 isolation.So we creatively solved the problems that troubled us...
